NBMSiDE Silicon Anode Material

NEO Battery Materials is a Canadian battery technology company listed on the TSX Venture Exchange (NBM). It develops silicon anode materials and silicon-enhanced lithium-ion cells to raise energy density and charging speed beyond graphite-only anodes, while keeping silicon's volume expansion and cost under control.

Its NBMSiDE anode uses a proprietary one-step, single-pot solution coating process that wraps each silicon particle in a composite nanocoating to manage swelling, without high temperature, high pressure or vacuum. The process works with low-cost metallurgical-grade silicon as well as silicon nanoparticles and is offered in grades P100, P200, P300 and P300N. NEO also runs a battery foundry that builds custom cells, such as a 307 Wh/kg 21700 cylindrical cell, for drone, robotics, electronics, automotive and data centre storage customers.

• One-pot coating process: single-step solution coating without high temperature, pressure or vacuum.
• Swelling control: composite nanocoating encapsulates each silicon particle.
• Low-cost feedstock: uses metallurgical-grade silicon microparticles as well as nanoparticles.
• Product grades: NBMSiDE P100, P200, P300 and P300N for different cell needs.
• High-energy cells: 6.3 Ah 21700 cell at 307 Wh/kg and an 11.5 Ah cell with UN 38.3 certification.
• Battery foundry: custom cell development and system integration services.

Drone and robotics manufacturers in Vietnam could commission custom high-energy cells from the battery foundry to extend flight and operating time. Local battery cell producers could test NBMSiDE grades as a silicon additive in graphite anodes to raise capacity. Electronics assemblers could co-develop compact cells for portable devices.

The company reports NBMSiDE specific capacity above 2,000 mAh/g, initial coulombic efficiency above 88% and an anode capacity gain of 40% to over 70% when blended into cells. It claims more than 60% lower cost than competing silicon anodes thanks to metallurgical-grade silicon and a single-step process, and its 21700 cell reaches 307 Wh/kg.

Drones, robots and portable electronics need lighter batteries with more energy, and silicon-blended anodes are one of the main routes to raise energy density without changing cell formats. Asian battery hubs in Korea and Southeast Asia are expanding cell production for drones, e-mobility and storage, creating demand for anode additives that can be adopted on existing lines.

NEO Battery Materials Ltd. describes itself as a Canadian battery technology company and is listed on the TSX Venture Exchange under NBM. In September 2026 it won a Grand Prize in the Innovation category at the K-Battery Show in Korea, secured a CAD 392,000 purchase order from a North American Fortune 500 automotive OEM and partnered with Korean drone maker Preneu for joint entry into Canada.
